I have a site to site VPN set up using a T1 internet connection on both sides and sonicwalls on both sides.
When running a ping test connection is never lost.
I have some programs that use oracle odac and oracle forms on the remote site that connect to the oracle 11 database on the home site and the programs will crash and give a ora-12571 TNS:packet writer failure.
I have already tried to change sqlnet.ora on the client, SQLNET.AUTHENTICATION_SERVICES= (NONE) from (NTS) and that did not resolve the issue. The disconnect seem to occur every 15 minutes or so.
Issue only occurs on site to site vpn setup. Connections to a different subnet using a MPLS connection are working properly.
Any help would be appreciated.
